EOS has developed four new metal powders for use with its EOS M 290 3D printer.

This includes two stainless steels, one tool steel and one nickel alloy.

EOS StainlessSteel 254 is an austenitic stainless steel that comes with a 40/60 µm process for the EOS M 290 system. It has high chromium, molybdenum and nitrogen alloying which improves corrosion resistance, according to the company. It also offers stress corrosion cracking and higher strength than conventional austenitic steel as well as resistance to uniform, pitting and crevice corrosion. The material is suitable for applications such as chlorinated seawater handling equipment, pulp, and paper manufacturing devices as well as chemical handling equipment.

EOS StainlessSteel SuperDuplex is an austenitic-ferritic duplex stainless steel which comes with a 40/80 µm process. According the company, it has high chromium, molybdenum and nitrogen alloying which again gives improved corrosion resistance, as well as resistance to uniform, pitting and crevice corrosion. It is suitable for applications in the oil and gas industry, in pulp and paper manufacturing devices and for mining and offshore equipment.

EOS ToolSteel CM55 comes with a 40/80 µm process and is cobalt-free, EOS says that it has high strength and high hardness and is therefore suitable for tooling and engineering solutions. It can also be used in demanding applications and in elevated temperatures. Suitable applications include cold and hot working tools, powertrain components and parts for mechanical engineering.

EOS NickelAlloy HAYNES 28 is a precipitation strengthened nickel-base superalloy which offers high temperature strength, thermal stability, good corrosion, and oxidation resistance, fabricability and improved weldability. It has been developed for high temperature structural applications and is manufactured under license from Haynes International. Typical applications range from aerospace and rocket engine components to turbomachinery and gas turbine parts, and to energy industry components.
